from Wikipedia, the free encyclopedia

A manifold is in the art, a pipe section, which by its curved shape a change in direction of fluids ( gases or liquids causes).


Various elbows in a pipeline

In pipeline technology , elbows are crucial components that are exposed to special loads in the event of pressure surges in the pipeline. Overloading, material defects or defects in weld seams can lead to fractures with considerable consequences.

Automotive technology

In automotive engineering there are intake manifolds and exhaust manifolds . These are bent pipes , usually one per cylinder , which forward the intake or exhaust gas flow, hence the distinction between exhaust and intake manifold.

Intake manifold

The intake manifold (also known as the intake manifold) directs the air drawn in by the engine or the mixture generated by the carburetor or injection system for combustion in the engine. Here, too, the curved shape is usually found, since the openings on the engine are on the side and the intake flow has to be deflected.

Exhaust manifold

Single pipe exhaust manifold

The exhaust manifold is a component of the exhaust system of internal combustion engines . Screwed directly onto the engine, the manifold forwards the exhaust gases from the mostly horizontal engine openings into the exhaust system below . The shape and number of manifold pipes per manifold system depends on the number of cylinders in the engine and the routing of the pipes on and under the vehicle. A manifold system can consist of many individual bends, sections, catalytic converters and W- or Y-shaped collectors or nodes.
